The conventional grain-oriented (CGO) silicon steel containing copper is a type of grain-oriented steel with low cost and high productivity. The processing parameters in CGO steels are quite different to those of low temperature heating and nitriding high permeability (HiB) grain oriented silicon steels. the fluctuation range of the magnetic properties in CGO is much higher than that ... https://www.rxkaitori.com/product-category/ge-bls-e-cmh-ballasts/
